SOLAR SYSTEM

Detailed explanation-1: -Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion. Like all orbiting bodies, comets follow Kepler’s Laws-the closer they are to the Sun, the faster they move.

Detailed explanation-2: -The secrets of what makes a comet, asteroid, or an object beyond our Solar System orbit the way it does? It’s simply gravity, and the gravitational interactions throughout its history. Objects stably in our Solar System, particularly after 4.5 billion years, are all moving in elliptical orbits around the Sun.

Detailed explanation-3: -The planets orbit the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The dwarf planets Pluto, Ceres, Makemake, Haumea, and Eris also orbit the Sun. Visit NASA Space Place for more kid-friendly facts.

Detailed explanation-4: -Comets and asteroids orbit the Sun similar to the way the Earth does. Scientists believe many of these small worlds have changed very little since they first formed. They are unlike Earth with all its weathering, volcanoes and earthquakes.

Detailed explanation-5: -Small objects like comets are pulled by larger objects in our solar system. A comet begins when something pushes it away from its starting point and into the wideness of space. Usually a comet gets pulled into space by a star traveling past, or a planet that is nearby. Gravity is what moves things in space.
